If you thought the set of Hollywood's next movie musical, The Greatest Showman, was all circus magic and family fun, think again.

Last month, a staged fire got out of control on the set of the star-studded movie. Luckily, stars Hugh Jackman and Zac Efron had already wrapped the precarious scene when the set piece went up in flames. The scene in question called for Jackman's character, legendary showman P.T. Barnum, to carry his assistant Phillip (Efron) out of a burning house.

According to Efron, he had no idea how intense the flames actually were until he watched the scene on playback.

"It started to get late, and some of the pyrotechnics got a little bit too hot," Efron told MTV's Josh Horowitz at CinemaCon on Tuesday (March 28). "We burst out of the building. It looked great on camera. We didn't know it [at the time], but it was pretty intense. I watched playback, and he saved me from a burning building. It later exploded that night. It was a set, but it later burned down."

"It was pretty awesome," he added. "Hugh Jackman saving you from a burning building? It's every girl's dream."

Um, I think you meant it's every man, woman, and animal's dream, Efron. Just think of how many kitties would love to be cradled by Hugh Jackman.

When MTV News caught up with Jackman at the New York premiere of Logan this past February, the man formerly known as Wolverine said Zefron was "heavier than he looks." Apparently, Efron didn't lose all of his Baywatch muscle in time for The Greatest Showman — not that we're complaining or anything.
